FRITZ LANDAUER, OF FRANKFORT-ON-THE-MAIN, GERMANY, ASSIGNOR TO THE FIRM OFXG. F. LANDAUER-DONNER, OF SAME PLACE.

VIENTILATOR FOR HATS.

SPECIFICATION forming part of Letters Patent No. 614,962, dated November 29, 1898. Application filed May '5, 1898. Serial No. 679,754. (No model.)

To all whom it may concern.-

Be it known that I, FRITZ LANDAUER, manufacturer of leather, residing at Frankfort-onthe-Main, Germany, have invented new and useful Improvements in the Manufacture of Ventilators for Hats, of which the following is a specification.

The present invention has for its object to enable the ventilation of a hat to be regulated as desired; and it consists of a ventilating device Which can be fully opened or entirely shut, as desired. This device is applied to or forms part of the usual hat-leather or sweatband, and is applicable to felt hats as Well as to straw hats.

The device consists, substantially, in providing a series of holes or slits in the hatleather and also in providing a flap whereby to close said holes or to leave them open. For this purpose a second piece of leather or a strip of any suitable material is combined with the hat-leather in such manner as to admit of being placed in front of the slits by turning the strip down onto the slits.

The device forming the subject-matter of my invention is illustrated in the accompanying drawings, wherein- Figure 1 is a face view of the device; and Fig. 2 is a longitudinal sectional view of the same, the said view being taken on the line 1 1, Fig. 1.

In the drawings, A is the hat-leather oi sweat-band, which is pierced by a row of equally-spaced apertures or slits a. For the purpose of closing said slits a flap G is stitched to the upper edge of the hat-leather A, so as to admit of being turned down to close the slits a, as shown. In order to open the slits a, the flap is turned up, so that it stands upright inside the hat, where it is out of the Way.

It will be observed that by my invention I am enabled to provide a simple, cheap, and efficient ventilating device for hats, wherein a single strip of material may be employed, and no mechanism whatever is necessary to adjust it.

Having now particularly described and ascertained the nature of the said invention and in whatmanner the same is to be performed, I declare that what I claim is- A ventilating device for hats comprising a slitted hat-leather, a strip connected therewith which is adapted to be folded down to cover the slits in the leather or to be turned up to leave said slits unobstructed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRITZ LANDAUER.
